I have a few Canon LBP251's that have a lot of paper mismatch errors. We only use letter paper in the office so there is no different size requested. It happens on all kinds of different documents as well. Word and PDF's. I have completely replaced a computer with brand new drivers as still same issue. I tried all the different type of drivers available on Canon's website as all have the error. I have the best results using PCL6 drivers but still happens. I am at a loss. Any ideas on how to troubleshoot why the printers keep having mismatch errors.
